[Ipopt] Ipopt Digest, Vol 135, Issue 2

[Brad Bell]

I do not know if this will help, but I have written an alternative 
derivative testing routine as part of a particular application of 
ipopt.  Perhaps the ideas in that routine would be helpful.

The documentation can be found at
http://moby.ihme.washington.edu/bradbell/cppad_mixed/ipopt_fixed_check_grad_f.htm

The source code can be found at
https://github.com/bradbell/cppad_mixed/blob/master/src/ipopt_fixed.cpp
in the routine
bool ipopt_fixed::check_grad_f(bool trace, double relative_tol)
